Enderreeper

The Enderreeper - The unholy offspring of ender and death has spawned in from the rift, after a thousand explorers recklessly used too much magic.

Spawning
Enderreepers exclusively spawn in the End, but are a rather common sight everywhere in the End. Though much rarer than the Endermen, their rapid approach makes their presence much more pronounced.

Design
The Enderreeper model was originally developed several years ago by the evil minecraft team (1.2.5) who, after abandoning the modding world, released all their code for everyone to use. After updating parts of the code over the years, the mod creator decided to release the Enderreeper as a special mob to commemorate his first 1000 downloads of Explorercraft.

The Enderreeper is a Creeper who has become infused with the ender, transforming and gaining significant new powers and strength in the process. It has lots of health, is lightning fast, and does enormous amounts of explosion damage. This monstrosity only spawns in the end dimension where the ender is strongest and does not venture into any other realm. If you do manage to kill this abomination, you'll be rewarded with gunpowder and ender pearls, though you are probably better off trying to escape their notice. If you had the foresight of putting Enderbane on your sword, then you'll stand much more of a chance.

'''Under any circumstances do not shoot the enderreeper with anything ranged! You have been warned!'''
